you need to pass vdso=0 to the kernel there.
I finally built a version of the 2.6.6 kernel that boots on FC1 with
vdso=0. I still see ALSA xruns while using Jack with realtime scheduling
(booting into 2.4.26 gives me rock solid performance in the same machine
/ distro).
Does the "nosysinfo" kernel boot option still turn off nptl globally?[*]

[*] others running 2.6.6 in Debian have also found problems with 2.6.6,
some of them where solved by disabling nptl with the LD_ASSUME_KERNEL
environment variable.
